Surgery Flashcards
What is the typical presentation of acute appendicitis? (4)
Abdo pain
Reduced appetite
Poss vom
Low-grade fever
Describe 3 features about abdo pain in acute appendicitis?
Central → RIF (less localised in younger)
Aggravated by moving (e.g. jump, cough, speed bumps)
Tenderness/guarding at McBurney’s
What are some features of an atypical presentation of acute appendicitis? (2) which may seem like other DDx
Diarrhoea + RIF pain (Gastroenteritis)
Abnormal urine dip (UTI)
What are some features of a late presentation of acute appendicitis? (2)
Abscess/palpable mass
Perforation
What is meckel’s diverticulum + what is its incidence in the general population?
What conditions may it lead to? (4)
How is it treated?
Ileal remnant of vitello-intestinal duct (gastric+panc)
2% all people
→ intussusception / volvulus (obstruction)
→ diverticulitis (abdo pain mimicks appendicitis)
→ lower GI bleeding
Tx: surgical resection
What is intussusception + what age group does it occur in?
Part of bowel invaginating into distal
B/wn 3m-2yrs
How does intussusception present? (3)
What are some late signs? (4)
Sudden episodes
Colicky pain
Abdo mass
Bloody/mucus (redcurrant jelly) stool (late sign)
Lethargy
Hypotonia
Shock
How is intussusception treated? (2)
Rectal air insufflation
If fails → surgery
What causes malrotation?
What is the commonest form/ what condition occurs as a consequence
How does malrotation present? (3)
How treated
Unfixed mesentery (duodenojejunal / ileocaecal) = shorter mesenteric base Caecal fixation to high posterior wall → Ladd bands cross duodenum (Obstruction) + Volvulus
Presents: Abdo pain, Bilious vomiting, Obstruction
Tx: urgent surgical correction
What is pyloric stenosis
What are the RFs ? (3)
What are the features/presentation? (5)
Pylorus hypertrophy → gastric outlet obstruction
RFs: Male (4:1), 1st born, FH (esp maternal)
2-7wks (regardless gestation)
Projectile + progressively frequent VOMITING
Hunger after vom → dehydration → lost interest (Wt loss if delayed)
Visible gastric peristalsis
What Ix are done for pyloric stenosis?
How is it managed? (2)
Test feed (palpable abdo mass + vom)
USS
U&Es (hyponat/kal/chlor)
Immediate fluid resuscitation (saline/gluc/K+)
Pyloromyomotomy (preserves mucosa)
What would be seen on AXR in duodenal atresia?
Double bubble + absence of air distally
How does an inguinal hernia occur?
What are the RFs (2) / incidence
Incomplete obliteration of processus vaginalis
Boys/ Premature (1 in 50 boys)
What situations would indicate more urgent surgery for inguinal hernia? (2)
Firm/tender/irreducible
Infant irritable/vomiting (risk strangulation/testes damage) (but delay 48hrs allowing oedema to resolve)
How does a hydrocele occur?
How does it present (5)
How managed?
Patent processus vaginalis (not wide enough for inguinal hernia but enough for peritoneal fluid to pass)
Present at birth /early childhood (post-viral/GI illness)
Asymp (usually bilateral) scrotal swelling
Transilluminable
Non-tender
Bluish discolouration
What is a varicocele?
How does it present? (2)
What are the complications? (2)
Varicosities of testicular vv’s
Usually L sided
Drag/ache/asymp
Risk impaired testicular growth / infertility
